CVE-2024-36332
Improper isolation of GPU HW register space could allow a privileged attacker in malicious Guest Virtual Machine VM to perform unauthorized access to specific victim range of GPU MMIO register space, potentially causing the host OS to reboot and creating a Denial of Service DOS condition...
SUSE CVE-2026-46022
In the Linux kernel, the following vulnerability has been resolved: misc: ibmasm: fix OOB MMIO read in ibmasmhandlemouseinterrupt ibmasmhandlemouseinterrupt performs an out-of-bounds MMIO read when the queue reader or writer index from hardware exceeds REMOTEQUEUESIZE 60. A compromised service...
SUSE CVE-2026-46064
In the Linux kernel, the following vulnerability has been resolved: ibmasm: fix heap over-read in ibmasmsendi2omessage The ibmasmsendi2omessage function uses getdotcommandsize to compute the byte count for memcpytoio, but this value is derived from user-controlled fields in the dotcommandheader...

Linux kernel 安全漏洞
The Linux kernel is the kernel used by the Linux operating system developed by the Linux Foundation in the United States. There is a security vulnerability in the Linux kernel, which stems from an out-of-bound MMIO read performed by the queue reader/writer index exceeding the REMOTEQUEUESIZE rang...
kernel: Linux kernel KVM: Privilege escalation or denial of service due to improper shadow page table entry handling
A flaw was found in the Linux kernel's Kernel-based Virtual Machine KVM component. A local attacker with privileges on the host system could exploit a vulnerability in how KVM handles shadow page table entries SPTEs during memory-mapped I/O MMIO operations. By manipulating guest page table entrie...
Astra Linux - уязвимость в linux-6.1
In the Linux kernel, the following vulnerabilities have been resolved: x86/tdx: Fixed the “in-kernel MMIO” check TDX only supports MMIO operations initiated by the kernel. The handlemmio function checks whether the VE exception occurred in the kernel and rejects the operation if it did. However,...
Astra Linux - уязвимость в linux-5.10, linux
In the Linux kernel, the following vulnerabilities have been resolved: RISC-V: Ensure that port I/O string accessors actually work properly. Fixed port I/O string accessors such as insb’, outsb’, etc., which use the physical PCI port I/O address rather than the corresponding memory mapping to...
Astra Linux - уязвимость в linux, linux-5.10
In the Linux kernel, the following vulnerability has been resolved: RDMA/siw: Fixed the issue where immediate work requests were flushed to the completion queue incorrectly. The opcode of the send queue element was set correctly during the flushing of immediate work requests in the post-sendqueue...
Astra Linux - уязвимость в linux-6.1
In the Linux kernel, the following vulnerability has been resolved: x86/tdx: Fixed a data leak in the mmioread function. The mmioread function calls a TDVMCALL to retrieve MMIO data for a given address from the VMM. Sean noticed that mmioread inadvertently exposes the value of an initialized...
Astra Linux - уязвимость в linux-5.10
In the Linux kernel, the following vulnerability has been resolved: drm/xe: Open-code GGTT MMIO access protection GGTT MMIO access is currently protected by hotplug drmdeventer, which works correctly when the driver loads successfully and is later unbound or unloaded. However, if the driver load...
